In a large skillet over medium high heat, bring the first 6 ingredients to a boil.
Turn the heat to low and stir in the honey. Once honey is incoporated, add the shrimp and the lemon slices and cover. Cook about 7 minutes or until the shrimp are uniformly pink.
Using a slotted spoon, remove the shrimp and lemon slices to serving bowls. Add the cold butter a couple of cubes at a time, whisking constantly while each addition of butter melts. This emulsifies the sauce.
Pour the sauce over the shrimp and garnish with scallions and parsley.
Serve with lots of French bread and napkins. Put a bottle of hot sauce on the table!
